  1. 1. Pharmacometric Methods and Novel Models for Discrete Data

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elodie L Plan; Mats O Karlsson; Laura Sargentini-Maier; Armel Stockis; Christian Laveille; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; pharmacodynamics; disease progression; modelling; discrete data; count; ordered categorical; repeated time-to-event; RTTCE; RCEpT; NONMEM; FOCE; LAPLACE; SAEM; AGQ; pain scores; epilepsy seizures; gastroesophageal symptoms; statistical power; simulations; diagnostics; PHARMACY; FARMACI; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Abstract : Pharmacodynamic processes and disease progression are increasingly characterized with pharmacometric models. However, modelling options for discrete-type responses remain limited, although these response variables are commonly encountered clinical endpoints. Types of data defined as discrete data are generally ordinal, e.g. READ MORE

  2. 2. Discrete Event Process Modeling of Manufacturing Systems Using Sensor Graphs

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tord Alenljung; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; State Estimation; Fault Detection and Diagnosis; Process Modeling; Discrete Event Systems; Logic Controllers; Formal Verification; State Feedback Control;

    Abstract : The design of control programs for manufacturing systemsis becoming more and more complex as the demands for flexibility,efficiency and reconfigurability increase, due tochanging consumer demands and fierce competition.There are methods stemming from academia that can assist the control programmersin facing these challenges.

  3. 3. Nonparametric tests for comparing two treatments by using ordinal data

    University dissertation from Örebro : Örebro universitetsbibliotek

    Author : Helen Wahlström; Elisabeth Svensson; Jan Lanke; Sture Holm; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistik; change; clinical trial; Monte Carlo; ordered categorical data; paired data; permutation test; Pitman efficiency; power; stratification; ties; visual analogue scale; Wilcoxon-Mann-Whitney statistic; statistik; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; Statistics; Statistik;

    Abstract : This thesis concerns four nonparametric tests for comparing two treatments in a randomized controlled clinical trial when the main response variable generates discrete or continuous ordinal data and measurements are made at baseline and follow-up.In the Wilcoxon-Mann-Whitney test (WMW) the baseline values are not taken into account at all, but in the other three tests both baseline and follow-up values are used.

  4. 4. Essays on Unit-Root Testing and on Discrete-Response Modelling of Firm Mergers

    University dissertation from Uppsala : Nationalekonomiska institutionen

    Author : Nikolay Angelov; Per Johansson; Steinar Strøm; [2006]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; unit root; structural break; LR test; stationary alternative; matching; firm mergers; discrete choice; Nationalekonomi; SOCIAL SCIENCES Business and economics Economics; SAMHÄLLSVETENSKAP Ekonomi Nationalekonomi; nationalekonomi; Economics;

    Abstract : Essay 1 investigates the time-series properties of the price of iron ore. The focus is on unit-root testing in the presence of a structural break. Unit-root tests with or without structural breaks are applied to historical prices of five different qualities of Swedish and Brazilian iron ore. Tests with exogenous or endogenous breaks are analyzed. READ MORE

  5. 5. Valuing environmental benefits using the contingent valuation method an econometric analysis

    University dissertation from Uppsala : Nationalekonomiska institutionen

    Author : Bengt Kriström; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental benefits; contingent valuation; econometrics; discrete response data; continuous and discrete valuation questions; cost-benefit analysis;

    Abstract : The purpose of this study is to investigate methods for assessing the value people place on preserving our natural environments and resources. It focuses on the contingent valuation method, which is a method for directly asking people about their preferences. READ MORE
